I noticed that ice cream was starting to melt in the freezer of my
1979 GE side by side Ref/Freez combo. I removed the frozen goods
and put them outside. I new there was a reason for this cold weather.

I had this problem once before and the drain in the freezer was frozen
and plugged. That is not the case now.

What I have noticed is the fan that is positioned to blow on the
compressor comes on from time to time but shuts down after only
running for about five seconds. I believe this symptom is related to
the problem I am having.

The refrigerator seems to be fine but I haven't put a thermometer
in it yet to confirm this. The unit seems to be fairly clean from dust
in the coils and the drip pan is dry.

Help. Any pointers to what the problem may be?

Hmmm 30 years. I believe GE used their "uni-bearing" cond motor.
The single bearing has probably gone oval-shape.

Dig out the model number, but this shows some common parts:

You could put a meter across the motor just to verify that
it is getting power when it stops spinning.

I have checked the temperature of the refrigerator now. It is to warm
also. I believe the separate cooling fan for the compressor shuts down
because the compressor is froze up and over current. Not having to
delve into a refrigerators working before this can only be a guess.

Maybe some one on this group can confirm whether the cooling fan runs
during the same time periods as the compressor. If so I may be off to
Lowe's to get another thirty year refrigerator.

More bad news if I am understanding the circuit. A bi-metal over
current device clicks off when the fan shuts down. This thimble sized
device is in series with the compressor and fan. If I unhook one leg
of the compressor the over current device will not trip and the fan
continues to run.

Ah. You are probably right then that it's a compressor failure.
That's the starting relay for the compressor.

Too bad.
